Reverse Osmosis Systems Manufacturer Solves Ro Membrane Low Temperature

BLOG_POSTED_BY caojing1120     २०१९ डिसेम्बर ५    

The Reverse Osmosis Systems Manufacturer(KOKOELECTRIC) tells you that there are several reasons for the low water output of reverse osmosis water purifier:

1. Membrane clogging

The membrane has been used for a long time, some for two, three or more years. According to the instructions, the life of the membrane is one and a half to two years. Water consumption and raw water quality should be taken into account for the service life of the membrane. Water consumption and raw water quality are generally proportional to the service life of the membrane.

2. Post-activated cotton jam

This situation usually occurs after the replacement of new post activated carbon. Because there is too much carbon powder, it has not been washed away. Therefore, the general granular activated carbon filter element cannot be filled too full (not to cut corners), and the filling space should be reserved to ensure water flow on the one hand and the activated carbon itself has an expansion coefficient on the other.

3. Low temperature

The water production rate of the RO membrane has a great relationship with the temperature, with the maximum heat not exceeding 40 degrees and the minimum not less than 5 degrees. The general optimum temperature is 25 degrees. Based on 25 degrees, the water yield will be reduced by 3% for every degree of reduction. Therefore, the water production speed in winter is generally reduced by half or more than that in summer. Users in rural areas need to pay special attention to cold protection and freezing prevention. Sometimes the filter bottles and membrane shells will be damaged in winter, and the outlet of the concentrated water pipeline should not be placed outdoors in winter.

4. The pump pressurization is small.

Pump pressurization is small, which generally occurs in reverse osmosis water purification machines with a service life of more than two years, or water purification machines that are in a working state for a long time. The water making principle of pure water machine is that the pump is pressurized and driven to the appropriate pressure required for water to pass through the reverse osmosis membrane. The domestic water purifier is generally about 6-7kg, and reverse osmosis commercial machine is generally about 4-6kg. Increased water consumption by users and pollution of water quality may shorten the service life of pumps.
